We have three orbiters and two rovers currently exploring Mars, each of which returns breathtaking photos on a daily basis.

The ever-vigilant Doug Ellison just posted this animation, which really actually does show a teeny tiny bit of motion in the right front wheel. If you don't notice any motion, look closer.

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a

It really looks like the second attempt at driving Spirit out of the trap has had the hoped-for result: some forward progress (maybe about a centimeter), and no evidence for further downward sinking.

Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.

Even though all of us rover fans know that Spirit is really, really stuck, I think I'm not the only one who was secretly hoping that today's images downlinked from Spirit would show that the rover had magically popped out of the ground overnight. Of course, she didn't.

Since A. J. S. Rayl was also listening in on today's press briefing about the efforts to extricate Spirit from her predicament at Troy, I'll just hit the high points and send you over to her story when she has posted it.

The Mars Exploration Rover Opportunity has been studying a lot of meteorites. That made me wonder, why study meteorites on Mars when we can study them in hand on Earth? How are Mars meteorites interesting?

It's been an awful long time since we've seen one of these from Spirit: an animation of four Navcam frames documenting motion!

There were some issues with the voting widget on the University Science Writing competition, but they have been resolved, and it turns out it was counting the votes all along! So go vote for my post if you haven't done so yet today!

Remember when I mentioned a few weeks ago that I submitted a blog post about MSL as an action-adventure hero to ScientificBlogging's science writing competition?

These Mars Reconnaissance Orbiter HiRISE images of the defunct Phoenix lander in the early dawn light of northern spring have been out for some time, but no one had accomplished the difficult task of locating the Phoenix hardware in them until this week.

Opportunity's been making tracks lately, with brief stops to check out a couple of meteorites. I thought this view of its surroundings on sol 2,034 (a couple of days ago) was neat.

MSL is like James Bond. Want to know why?

Next up in my series of posts about the instruments on MSL is the Mars Descent Imager (MARDI).

I wonder if this came from the same original body as Block Island, or if Meridiani is the kind of slowly deflating landscape that accumulates meteorites at its surface, like the ANSMET meteorite hunting spots in Antarctica?

Last time, I talked about the MastCam color cameras on MSL, so it only makes sense to continue with one of the other cameras: The Mars Hand Lens Imager (MAHLI).

Opportunity rover is driving, driving, driving. It departed the meteorite named Block Island on sol 2,004 and has routinely clocked 70 meters per driving day (with drives every other day).

Doug Ellison has done it again: he's created a spectacular overflight of Gusev crater based upon digital elevation models of the terrain produced by the United States Geological Survey from HiRISE data.
